4 Claims.

This invention relates to spinning rings, and more particularly to animproved spinning ring arrangement by which the ring is mounted forrotation during the spinning operation so that the relative rotation ofthe traveler on the spinning ring can be substantially reduced to lessencorrespondingly the strain and attrition imposed on the yarn by thetraveler.

Also, according to the present invention, the spinning ring is arrangedto be driven during the spinning operation so that the relative rotationof the traveler on the ring can be regulated and controlled.

These and other features of the present invention are described furtherbelow in connection with the accompanying drawings, in which:

Fig. 1 is a fragmentary perspective view illustrating the disposition ofspinning rings on the ring rail of a spinning frame in accordance withthe improved arrangement of the present invention;

Fig. 2 is a sectional detail of the spinning ring assembly;

Fig. 3 is a'fragmentary side elevation, largely diagrammatic,illustrating 'the arrangement of the driving means for rotating thespinning rings; and

Fig. 4 is a corresponding horizontal section taken substantially on theline 44 in Fig. 3.

Referring first to Fig. 1 of the drawings, a usual form of ring rail isshown at l disposed for operation in relation to spindles l2 (only oneof which is shown) driven at whorls l4 by tapes as at H5. The spindlesi2 support yarn carriers l8 on which yarn 20 is taken up to build abobbin 22 during the spinning operation.

The yarn 20 is led onto the bobbin 22 through a traveler 24 which iscarried on the spinning ring 26, and which is pulled around the ring 26as the yarn is wound on the carrier l8 by rotation of the spindle l2. Inaddition to leading the yarn 20 onto the carrier [8, the traveler 24also serves the purpose of introducing a twist in the yarn, and duringthe spinning operations the ring rail I0 is actuated so that it has acyclic up and down motion regulated to lay the yarn 29' i. e., of theorder of several thousand revolutions per minute, which in turn resultsin severe strain and attrition on the yarn. This circumstance makes itnecessary to restrict the size (1. e., diameter) of ring used for agiven spinning operation within rather close limits in order to maintaina favorable angle of pull on the yarn through the traveler. Thisrestriction of the ring size in turn restricts the size of bobbin thatcan be built, which is an important disadvantage from the standpoint ofboth cost and production, and the seriousness of this problem has beensubstantially increased by the modern trend toward high speedoperations.

According to the present invention this problem is largely obviated byarranging the spinning ring 26 for rotation on the ring rail ID, asmentioned above, so that the relative speed of travel of the traveler 24may be substantially lessened, and thereby allow the size (1. e.diameter) of the ring to be increased to permit substantially largerbobbins to be built. This is done by providing a ring holder 28 adaptedto be fixed on the ring rail i 9, and which forms a bearing race as at28' (compare Figs. 1 and 2). The spinnin ring 26 is then mounted forrotation in this holder 28, being likewise formed for this purpose witha bearing race portion 26', and thereby adapted for assembly with theholder 28 on ball bearings 30 or the like.

The spinning ring 25 is further formed according to the presentinvention with a depending flanged portion as at 32 providing a pulleyadapted to be driven for rotating the ring 26 in the holder 28. Drivingmeans for the pulleyportion of this ring 26 may be convenientlyassociated with the spinning frame drive. A suitable arrangement forthis purpose is illustrated in Figs. 3 and 4 in which a driving drum 34is shown disposed on the spinning frame adjacent one end of the ringrail I0. This driving drum 34 may be fitted with a suitable ulley orwhorl as at 36 so as to be driven in turn by a tape or the like (notshown) just as the spindles I2 are driven druing the spinning operation.From the driving drum 34 then a tape 38 may be extended beneath the ringrail Ill and trained around the pulley portions 32 of each ring 26 asindicated best in Fig. 4. Tension rolls 40 may be disposed as shown tomaintain the tape 38 taut on the pulley porsions 32, and a suitableshipper as indicated at 42 may be arranged on the ring rail l0 so thatthe tape 38 will be shifted on the driving drum 34 in accordance withthe cyclic up and down motion of the ring rail.

An arrangement of this sort makes it possible to obtain nice regulationand control of the ring and traveler during the spinning operation, and.if desired, a variable speed adjusting means (not shown) may be providedto control the driving drum 34 and thereby provide for variableregulation of the speed of the traveler during the spinning operation.

I claim:

In a spinning frame, a vertically movable ring rail, an upstandingdrum arranged near one end of the ring rail for rotation at a givenelevation, a group of rings extending longitudinally of the rail, aholder surrounding each ring and held stationary upon the rail, theholder and ring having races, bearing elements held within the races, awide pulley secured to each ring and extending downwardly below the ringand holder and having an approximately flat face, a wide flat beltextending longitudinally of the rail and engaging a plurality of thepulleys to drive them and passed about the upstanding drum to be driventhereby, means to shift the belt vertically with the movement of therail so that the belt is shifted longitudinally of the drum, and meansto drive the drum.

2. In a spinning frame, a vertically movable ring rail, an upstandingdrum arranged near the ring rail and separate therefrom to rotate at agiven elevation, a group of rings extending longitudinally of the rail,a holder surrounding each ring and held stationary upon the rail, theholder and ring having races, bearing elements held within the races, awide pulley secured to each ring and extending downwardly below the ringand holder and .having an approximately flat face, idler pulleys spacedfrom the ring pulleys and mounted upon the rail, a wide flat beltextending longitudinally of the rail and engagin faces of the ringpulleys and opposite faces of the idler pulleys and passed about theupstanding drum to be driven thereby, means to shift the belt verticallywith the movement of the rail so that the belt is shifted longitudinallyof the drum, and means to drive the drum.
